I know it's a bit late to be posting about this, and probably most people affected by this problem have resolved it, but I thought I'd add my experience regarding this problem on a SL 3.5 installation that has had various packages updated via Entropy and Portage (I also updated the kernel to 2.6.27 using genkernel) over the last couple of months. (I know it's not a stock SL 4.0/4.0-r1 installation, but the problem with the touchpad appears to be identical or very similar to what people experienced with 4.0/4.0-r1.)
I found that a USB mouse still worked perfectly on my Acer TravelMate 8215WLMi laptop, but the touchpad no longer worked at all (it was neither possible to move the cursor nor possible to select via tapping). I tried all the various fixes posted in the SL forums and the only thing that worked in the end was the following:
1) Edit /etc/make.conf and add the line INPUT_DEVICES="evdev keyboard mouse synaptics" (as the current line INPUT_DEVICES is commented out and has too many devices).
2) emerge -C x11-drivers/synaptics (I
had to do this, as this package was blocking the installation of x11-drivers/xf86-input-synaptics and the touchpad was not working with it, even with the various suggested fixes)
3) emerge -1v x11-drivers/xf86-input-synaptics
4) Edit /etc/X11/xorg.conf and add the following line:
- Code: Select all
Option "TapButton1" "1"
so that the InputDevice section in xorg.conf now looks like this (the format is otherwise
exactly as installed -- notice the incorrect order of some of the lines):
- Code: Select all

EndSection
Section "InputDevice"
I made only one change to the file /usr/share/hal/fdi/policy/10osvendor/11-x11-synaptics.fdi: I uncommented the line regarding input.x11_options.SHMConfig as shown below, although I believe this makes no difference to the ability to tap on the touchpad:
- Code: Select all

Anyway, I can again use the touchpad to move the cursor, tap once to select, tap twice and drag to scroll, and also two-finger-scroll vertically. As x11-drivers/synaptics is not installed any more and x11-drivers/xf86-input-synaptics is installed, I assume the two drivers are incompatible. Does anyone have any idea about this? KSynaptics no longer works, though, and trying to re-merge it fails. Anyway, everything else appears to be working correctly. It seems that the various synaptics software and the way functionality is apparently shared between xorg.conf and /usr/share/hal/fdi/policy/10osvendor/11-x11-synaptics.fdi is a real mess. Also, why are there two synaptics drivers (x11-drivers/synaptics and x11-drivers/xf86-input-synaptics)?
